Western Geomancy — the Renaissance / Golden Dawn geomantic HOUSE CHART (Agrippa → Cattan → Fludd → Heydon → the Golden Dawn → Greer). The 16 binary figures are cast into a shield (Mothers → Daughters → Nieces → Witnesses → Judge), then the first twelve figures are projected into the 12 ASTROLOGICAL HOUSES and the question is judged like horary astrology — by PERFECTION between the querent (House 1) and the quesited (the house of the topic): occupation > conjunction > mutation > translation, or denial (no). The yes/no is then coloured good or bad by the two significators' natures. Distinct from Rammal & Khatt, which read only the Islamic shield's Judge — this adds the entire European astrological-house layer. From a question + topic (or explicit quesited house) it returns the shield, the 12-house chart (Greer sequential mapping, each figure with element, planet, zodiac sign, points, meaning), the perfection judgment, the Court (Witnesses, Judge, Reconciler), the Part of Fortune (sum of the 12 house figures' dots mod 12), the Via Puncti (the Way of the Point — the single Fire point traced from the Judge to its root figure), and a 0–100 symbolic score. Deterministic from the question, date & name (or an explicit manual cast). Honest: the house mapping is the Greer/traditional sequential method (the Golden Dawn proper uses different placements); the Part of Fortune is mod 12 and not restricted to even houses; figure signs are tradition-variable; symbolic divination, not prediction. Locked against the Digital Ambler worked shield and gold perfection cases.
